Description

FIELD OF THE INVENTION

[0001] The present invention relates to the technical field of sanitary ware, and in particular to a deodorant sewer pipe.

BACKGROUND OF THE INVENTION

[0002] Deodorant sewer pipes in the related art are usually configured to have a S-bend and a P-bend, in which deodorization is achieved through water sealing. However, if the sewer pipe is not used for a long period of time, the water will dry up so that the deodorization cannot be achieved, and a situation of foreign matter blockage will occur.

SUMMARY OF THE INVENTION

[0003] To this end, the present invention provides a deodorant sewer pipe to solve the problem that the water will dry up and the deodorization cannot be achieved if the deodorant sewer pipes in the related art are not used for a long period of time.

[0004] In order to achieve the above object, the present invention provides the following technical solutions.

[0005] According to the present invention, a deodorant sewer pipe is provided, which includes a sewer pipe body, a universal sewer pipe and a deodorizer, wherein the sewer pipe body is connected to the universal sewer pipe, and the deodorizer is disposed in an interior of the sewer pipe body; the deodorizer includes a spring and a cover, and the spring is sleeved over the cover; when there is a water flow, the spring and the cover move downward to achieve drainage, and when there is no water flow, the cover is reset through an elastic force of the spring so as to block the sewer pipe body and achieve deodorization.

[0006] Further, the cover includes a connecting portion and a blocking portion, wherein the connecting portion is disposed perpendicular to the blocking portion; the connecting portion is cylindrical, and the spring is sleeved over a side face of the connecting portion.

[0007] Further, the blocking portion is in the shape of a disc, and a material thereof is silica gel or plastic.

[0008] Further, the deodorant sewer pipe further includes a screw, which is installed on the connecting portion and installed in an axial direction of the connecting portion.

[0009] Further, the deodorant sewer pipe further includes a first O-ring, which is disposed on a connection face of the sewer pipe body and the universal sewer pipe.

[0010] Further, the deodorant sewer pipe further includes a second O-ring and a universal sewer pipe adapter, and the second O-ring is disposed on a connection face of the universal sewer pipe and the universal sewer pipe adapter.

[0011] Further, the deodorant sewer pipe further includes a third O-ring, which is disposed on a side face of the universal sewer pipe adapter.

[0012] Further, the number of the third O-ring is more than one, and the third O-rings are disposed at intervals on the side face of the universal sewer pipe adapter.

[0013] Further, the deodorant sewer pipe further includes a hexagonal adapter and a hexagonal lock nut, wherein the hexagonal lock nut is connected to an upper end of the sewer pipe body, and the hexagonal adapter is installed inside the hexagonal lock nut.

[0014] Further, the deodorant sewer pipe further includes a first rubber pad and a second rubber pad; the first rubber pad is disposed inside the hexagonal adapter, and the second rubber pad is disposed on a connection face of the hexagonal adapter and the hexagonal lock nut.

[0015] The present invention has the following advantages.

[0016] In the present invention, by disposing the deodorizer in the interior of the sewer pipe body, an automatic blocking and deodorization can be achieved under the action of the spring. When there is a water flow passing through, the cover and the spring will move downward under the action of the gravity of the water flow, and the spring will be compressed so that water flows out all around the cover to achieve drainage. When there is no water flow, the spring will change from the compressed state to a free state, so that the cover is reset and blocking is achieved, thereby preventing the odor from upsurging. The phenomenon that the water will dry up in the toilet and the deodorization cannot be achieved if the deodorant sewer pipe is not used for a long period of time can be avoided, and there will be no blockage of foreign objects.
